The date can also vary slightly due to the gravitational influence of other celestial bodies, such as the Moon and Jupiter, which can tug on Earth and shift the timing of perihelion by a few hours.
In fact, perihelion occurs during winter in the Northern Hemisphere, around January 4th, while the Southern Hemisphere experiences summer. This apparent paradox is due to the fact that Earth's axial tilt and orbital plane are not aligned. As a result, the distribution of solar energy throughout the year is not directly correlated with the distance from the Sun.
This shift in speed has a noticeable effect on our calendar seasons:
| Event | Date (approx.) | Distance from Sun | Northern Hemisphere Season | | :--- | :--- | :--- | :--- | | (Closest) | January 2-5 | ~91.4 million miles | Winter (Cold) | | Aphelion (Farthest) | July 4-7 | ~94.5 million miles | Summer (Hot) |
Because this number is so close to zero, Earth's orbit is nearly circular, but that slight variation still accounts for a difference of millions of kilometers throughout the year. The Two Extrema: Perihelion and Aphelion when is earth closest to the sun

By analyzing the Earth's orbital parameters and the effects of perihelion on our planet's climate and environment, we can gain a deeper understanding of the complex relationships within our solar system. The study of perihelion serves as a reminder of the dynamic and ever-changing nature of our celestial neighborhood.
Perihelion is not a fixed date on the calendar, but it always falls within the first few days of January.
Meanwhile, the Southern Hemisphere is tilted toward the Sun in January, which is why they experience their peak summer during perihelion. Does Perihelion Affect the Weather at All? The date can also vary slightly due to
Understanding that Earth is closest to the Sun in January is a fun reminder of how astronomical mechanics, specifically the tilt of the planet, dictate our seasons more than simple proximity.
Our planet is tilted relative to its orbital path.
While the elliptical shape is subtle, the difference in distance is measurable:
Earth reaches its closest point to the Sun, or perihelion, around each year. As a result, the distribution of solar energy
In reality, seasons are caused entirely by .
Scientists measure how stretched out an orbit is using a term called . A perfect circle has an eccentricity of zero. Earth’s orbit has a very low eccentricity of about 0.0167. This means our orbit is nearly circular, but that tiny deviation is still enough to cause a 3-million-mile variance in distance over the course of a year. Distance vs. Seasons: The Great Misconception
This specific point in Earth’s orbit is known as . When is Perihelion in 2026?
In the 16th century, Johannes Kepler's laws of planetary motion provided a fundamental understanding of the Earth's orbit around the Sun. Kepler's work laid the foundation for modern astronomy and the precise calculation of perihelion.
This point in Earth's orbit, where we are closest to our star, is called . When is Perihelion in 2026?
The Earth's orbit around the Sun is an elliptical path, which means that the distance between our planet and the Sun varies throughout the year. At certain times, the Earth is closer to the Sun, and at other times, it is farther away. This report aims to provide information on when the Earth is closest to the Sun, a phenomenon known as perihelion.
